! allie/10m 'it may cof/cern Be itfknown that I, ALBERT citizen ot the United States, residing at i..alze Forest, in the county of Lake and State 'ot llinois, have invented. certain new and use itl iiiiliioveineiits in Printing U paratns,oi which the following is a speeltication. A l I I 'lliis invention relates to printing apparatus, and especially to priiiti-iigdiaohi-nes tor use inoiiices in printing 'iple epies 2F99 written wor-li, -for which use the apparatus would generally be operated by an unskilled person. l

'lheobject-ot the invention is to effect certain improvements in theconstruction of apparatus or' this character, particularly with respect .to the means :tor supporting the lines oi' type, to the end that superior results may be obtained, the amount oi power requiredv in operating the Aprinting- Inachine reduced, and the work of setting up the type and arranging Athem in the machine for printing facilitated.

The invention involves the use of a typeiorm in which each line oi type may be assembled and supported as a unit, that is, independently of the other lines. each line oiltyipe in the form consists of a holder and type mounted thereon, this thereon being typehigh, so that it'inay be used. in thev same :torni with type of ordinary construction or.

with an electrotype. These holders are of a special construction, devised to secure low .manufacturing cost thereof, to facilitate assemblage of the ty Y ethereon, and to properly hold the type uring the printing operation.

l will first describe the construction of the devices which l prefer to employ and will then point out how these may be used and the advantages secured thereby, referring tothe accompanying drawings, which show the preferred embodiment of the 1nvention.

ln these drawings, Figure l is aside elevation of one of the type-holders with type mounted thereon; Fig. 2 is a view similar to Fig. l, broken away in part; ig. 3 1s a top view ot the holder; ,Fig Il 1s a tra-nsverse section of the same; Fig. 5 is a view similar to Fig` 4E, illustrating a slight modi- B. Dion, a

To this end,-

iication; and Fig. 6 is a view illustrating certain portions of a printing mechanism and showing the manner in which the type. holders may beemployed.

Referring to these drawings, thetypcform consists of a'plurality oi lines ot type, the type of each line being mounted upon a holder, so that each line ot' type' maybe set up and positioned in the torni as alunit, independent of the other lines. Each holder with its type is'type-high, so that when de sirable the 'form may be made up in whole or in part of the line-units showinas in* some cases it may be desirable to have a portion ot the form consist' of type of the usual length or of one or more electrotypes. The holder for the line of type consists of' two thin metallic plates 1 and secured together side by side and. having a'dovetail groove formed in the upper edge thereof, adapted to receive the type 4. The two strips l and Q are similar and are ot uniform cross-section from end to end, with the exception that one or both of the ends of the groove are enlarged slightly, asshown at 5, to facilitato theentranoe of the type into the `groove. The -formation` ol' the holder from two similar strips in the manner indicated offers iinportant advantages. A holder provided with a dovetail groove in the upper edge thereof may be. constructed in this manner vat much less. cost than by making it from means for securing the two strips together' may be such thataiter a line of type has been set up upon aholder the strips may be drawn together so as to grip the type rigidly between them. Whether the type be gripped rigidly or not, they will be supported in a definite vertical position with respect to the holder, by reason of the shoulders G on. the type coacting with the upper edge ot the holder, and when so supported their printing faces will be type-high.

ln the accompanying drawings, l. have shown screws 7 as a means for securing the pieces l and 2 together and for drawing them together to such extent as to cause them to grip the type in the groove Fur thermore, I provide means whereby, when the screws 7 are loosened slightly, the plates l and 2 will vloe iiorced apart, so as to release .l their grip upon the type. Certain ci the lower ends of the a single strip of metal, and :furthermore the scret orten-ding between" the two plates 1 and 2 have springs B coiled thereon and vlying incountersin'ks 9, "these-`springs.'serv-' ing tojspread the plates 1 and" 2 when the screws 7-iare-loosened Fig. 5 showsa slight modification of the construction"Qabovedescribed, wherein the sides of' the :dovetail groove in i the type? holderarejinelned, -so that whenV the plates are drawnrv together the` type. .will b'e drawndownwardly to* cause their shoulders 6 to bear upon'theoupper ffice of the type-holder.

'- f- The"cons truction hereinshown for the type-holderis such that the' operationof set`v ting up and distributing the'type is greatly v`facilitated-. ,.A. holder such as that herein shown vmay 'be mounted upon an automatic 'type-setting machine,"the operation of which causes the type to pass one after another into' the upper endlof the vdoverail Vslot 'in the holden: After -aline has been completely set up, a' small block of rubber `10 maybe made to slide into the end of the groove and against the end type of the line, to 4prevent` movement ,of [the type lengthwise ofthe holds-ifi.l The passage 'of the type into the groove is lfacilitated by the inclined sides of the groove at the end-thereof, as shown at 5.

vmovement of. one type-holder relatively to another. Inkisfsupplied to the printing faces of the type'by a ribbon 17 and theim'- pression'sareeectedby airoller 18 adapted to rotate` and to move bodily' over theform ojtyp'e and' .li n'coaction with the printing. faces of the type through the impressionsheet` and ink-ribbon. With the lines of vtype arranged in' line-holders as above described, each line may move relatively to the adjacent lines in the direction'of the length l ofthe typeas the pressure-roller comes into Acoaction with the line, such movement being -permittedby the 'resilient pad 15. For thisv reason, a pressure-roller having a relatively.. hard surface may be employed and thus embossing of the .impression-sheet avoided. Also, a lighter pressure of the roller upon the type will be su'icient Ato give the desired results. L-'Furthermore, by reason of the lighter pressure employed, the power necessary to drive the'machinelis decreased and less arring of the parts .of the machine takes place. Y

lI-laving now described my invention, what Iclaim as new therein-and desire toseoure byLetters Patent-is as follows 7 A formof type comprising a, plurality of type-holders and a line of vtype supported upon each type-holder, each type-holder withits .type being typeh'igh, and each typ-holder consisting of two disconnected' metallic strips of .uniform cross-sectior'r` throughout, lying side by side and having a lengthwise dovetail'groove in the upper edge thereofto receive the type, screws ypassing through said strips for drawing the strips together to grip the type, each-screw having its head. countersunk in one of the strips, and springs interposed between the'strips for vsepara-ting the strips to release the' type screws,substantially as set forth.

This "specification fsigned and witnessed when such separation ispermitted by said ALBERTB. DICK.
